A note on efficient computation of the multilinear extension

RD Rothblum - Cryptology ePrint Archive, 2024 - eprint.iacr.org
The multilinear extension of an $ m $-variate function $ f:\{0, 1\}^ m\to\mathbb {F} $, relative
to a finite field $\mathbb {F} $, is the unique multilinear polynomial $\hat {f}:\mathbb {F} …

More optimizations to sum-check proving

Q Dao, J Thaler - Cryptology ePrint Archive, 2024 - eprint.iacr.org
Many fast SNARKs apply the sum-check protocol to an $ n $-variate polynomial of the form $
g (x)=\text {eq}(w, x)\cdot p (x) $, where $ p $ is a product of multilinear polynomials …
